I also use the Aerobika for all the same reasons ( ease of cleaning, use with the nebulizer) plus it withstands all the taking apart, cleaning, and reassembly that needs to be done so often. I tried the Acapella (provided and paid for by insurance) for a while and each time it broke so easily. So, I pay out of pocket for the Aerobika but it is a much better product.
Also, @carolj68, I use the Chicco baby bottle warmer/sterlizer the same as you! It's small and fits all the parts just right. All the other baby bottle sterlizers were like large countertop appliances and way to bulky!
